Samsung Galaxy users report connectivity failures following One UI 9 update
Samsung Galaxy device owners are experiencing widespread Wi-Fi and SIM card recognition errors after installing the latest One UI 9 software update.
Users of several Samsung Galaxy models, including the S24 Plus, Z Fold 7, and A-series handsets, have reported significant connectivity issues following the rollout of the One UI 9 operating system update. Complaints indicate a pattern of persistent Wi-Fi drops and, in some cases, the inability of devices to recognize SIM cards.
Reports suggest that the errors are software-related, as users attempting standard troubleshooting steps—such as resetting network settings or restarting devices in safe mode—have not seen a permanent resolution. While some users report partial functionality on 2.4GHz Wi-Fi networks, 5GHz connections frequently fail or disconnect intermittently.
The widespread nature of these reports across multiple models points toward a bug within the One UI 9 firmware rather than hardware failure. Samsung has yet to provide an official statement or a timeline for a software patch to address these stability concerns.
